Unreal Engine

Copy the plugin from the repository into your Unreal Engine project's Plugins directory, then enable it in the Unreal Editor under Edit > Plugins.

cp -r Unreal_mcp/plugins/McpAutomationBridge/ YourProject/Plugins/

Open Edit > Project Settings > MCP Automation Bridge and confirm the host and port settings. The built-in HTTP server starts automatically when the plugin is active.

If you prefer the npm-based bridge instead of the native plugin, clone the repository and run the server with npx.

npx unreal-engine-mcp-server
# Or from source:
git clone https://github.com/ChiR24/Unreal_mcp.git
cd Unreal_mcp && npm install && npm run build
node dist/cli.js

Configure the bridge connection using environment variables. UE_PROJECT_PATH is required; the other variables default to localhost:8091.

export UE_PROJECT_PATH=/path/to/YourProject/YourProject.uproject
export MCP_AUTOMATION_HOST=127.0.0.1
export MCP_AUTOMATION_PORT=8091
export LOG_LEVEL=info

Register the Unreal Engine MCP server in claude_desktop_config.json. The server uses HTTP transport and connects to the running UE5 bridge.

{
  "mcpServers": {
    "unreal-engine": {
      "command": "npx",
      "args": ["-y", "unreal-engine-mcp-server"],
      "env": {
        "UE_PROJECT_PATH": "/path/to/YourProject.uproject",
        "MCP_AUTOMATION_HOST": "127.0.0.1",
        "MCP_AUTOMATION_PORT": "8091"
      }
    }
  }
}

Launch your Unreal Engine project. Once the McpAutomationBridge plugin is active and the MCP client is connected, ask Claude to list available actors or assets to confirm the integration works.
